Event Timeline

This revision is now accepted and ready to land.Mar 6 2019, 18:50

Just port hardening at once. Right now there are no way to check if hardening is ported properly and as this diffs proves, individual steps seems to be broken.

Fabien planned changes to this revision.Mar 13 2019, 14:52

Superseeded by D2687, can be removed when landed.
